滨海核电厂厂址附近海鸟外照射剂量率计算方法的比较研究

Comparative Study on Calculation Methods of Dose Rates of External Exposure of Seabirds Near the Sites of Coastal Nuclear Power Plants

使用ERICA程序进行辐射影响评价时,水生生态系统的参考生物仅考虑水体及沉积物对其产生的外照射,其中对于海鸟假设其完全浸没于水中,而ICRP相关出版物中的计算模型考虑得较为全面,对于海鸟考虑了水中、地表、地上和空气浸没的外照射,本文比较了ERICA模型和ICRP模型的不同,并以我国某滨海核电厂为例,分别使用两种模型计算海鸟受到的外照射剂量率,结果表明,ERICA模型的计算结果相对保守,从筛选评价的便捷性考虑,ERICA模型更为适用。

Using ERICA program for evaluation of the effects of radiation,water and sediment are only considered in the external exposure of aquatic reference organisms,and assuming seabird completely submerged in water,but the calculation model of related ICRP publication considers more comprehensively,and external exposure of seabirds considers the situation in water,on soil,above soil and immersion in air.In this paper,the ERICA model and ICRP model are compared,and taking a coastal nuclear power plant as an example,external exposure dose rate of seabirds is calculated by ERICA model and ICRP model respectively.The results show that the ERICA model is more suitable for the convenience of screening and evaluation.
